MINE-BUCKET-#DUMPING ATTACHMENT.

Application filed September 19, 1907.

To all whom it 'may concern:

Be it known that I, MICHAEL M. CALLA- GHAN, citizen of the United States, residing at Columbia, in the county of Esmeralda and State of Nevada, have invented certain new has been necessary to employ a man at the yao collar of the shaft to swing the bucket to one side so as to permit it to be dumped without any of the soil and water running back into the shaft, a part of such mans duties being the closing of a door at the collar of the shaft so as to protect the workmen in the shaft from the liability to injury from any of the material in the bucket falling back into the shaft. As noted, this work of looking after the doors and removing the bucket to one side requires the services of at least one man.

It is the primary object of my invention to provide a bucket hoisting mechanism which will do away with the necessity of the doors at the collar of the shaft and the services of the man, or men, at such collar required to swing the bucket to one side preparatory to dumping the same, and to this end, the invention consists essentially in a gallows frame embodying bucket guiding and dumping mechanism which will deflect the bucket in its upward traverse from the shaft collar and carry it to one side, the required or-predetermined distance, automatically in the -operation of hoisting and to also provide means for permitting the bucket to automatically dump itself after being hoisted, to be held securely to one side of the mine shaft until it is desired that it shall be again lowl ered into the latter, and to provide means whereby the bucket may be released from the holding means and expeditiously lowered into the shaft, all as will be hereinafter fully described and claimed.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

spective view of parts of the apparatus; Fig. 3 is a fragmentary elevation of a portion of the apparatus, illustrating the mine bucket in the proper position for riding upon its beams and, Fig. 4 is a detail side elevation illustrating trip devices arranged to permit the bucket to pass downwardly again into the shaft after it has been dumped.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the lining of a shaft above which the gallows frame is mounted. This frame may be constructed in various ways, so far as its general structure for supporting purposes is lconcerned and in the present instance it embodies the sills 2, uprights 3, cross beams 4, upper longitudinal beams 5 supported on the upper ends of the posts or uprights 3, and the braces 3aL secured to two of the posts and to extensions of the sills 2.

The shaft lining 1 is provided at opposite sides with the vertical rails 6 which, in the present instance, join at the collar of the shaft, the lower ends of inclined rails supported within the framework and carried off obliquely at the desired angle and to the required height according to the requirement of the case and the size of the framework.

A cross head 8 is mounted for movement along the rails 6 and inclined rails 7 of my invention, said cross head preferably embodying spaced beams 9 that are formed with openings 10 through which the hoisting cable 11 passes. Preferably, also, the cross head 8 is formed with rollers 12 to reduce friction, and to insure the positive and easy traverse of the cross head from the vertical portions of the rails to the inclined portions thereof, and vice versa.

The cable 11 passes over the sheave 13 journaled in the longitudinal beams 5 at the top of the framework and may be secured at one end to any windlass or hoisting mechanism. The bucket 14 has its bail 15 secured to the other end of the cable 11 and preferably the said cable is provided With a stop 16 of any desired construction, designed to limit the independent movement of the cable through the cross head at the required point, it beingthe purpose of the cross head to steady the bucket in its passage up and down the shaft.

Underneath the inclined rails 7, inclined bucket supporting beams 17 are secured within the framework. The upper shaft sheave 18 at the collar of the shaft is journaled between the lower ends of these bucket supporting beams 17 and the cable is designed to pass over such sheave, in the customary way. The bucket 14 is provided, preferably near its bottom with diametrically opposite outwardly projecting arms 19 designed' to slide along the beams 17 as the bucket is raised and lowered within the framework. At the upper end of the shaft lining 1 inclined deflectors 20 and 21 are secured, said deflectors being arranged in substantially V-shape, as shown, with a space between their lower ends and with their upper ends contiguous to the lower ends of the respective bucket supporting beams 17, the space between said deflectors being provided as a passage for the hoisting cable, and one of said deflectors being preferably longer than the other, so as to prevent either of the arms 19 of the bucket from wedging in between the said defiectors. It is the function of these deflectors to engage either one of the arms 19 of the bucket, as the latter is being hoisted, so as to positively turn the bucket into a position where its two arms will engage with and slide along the beams 17. The beams 17 are provided at their lower ends with ledges 22 of sufficient width to support the bucket between them, but beyond these ledges the beams 17 are set far enough apart to permit the bucket to drop between them and swing freely on lthe arms 19. AThe beams 17 are provided above the ledges 22 with sockets 23 and with side recesses 24 contiguous to said sockets, trips 25 being pivoted within the recesses with their lower ends weighted so as to swing normally into a position where their upper ends will project above the slide surfaces ofthe beams.

In the practical operation of my improved hoisting mechanism and bucket dumping attachment therefor, from the foregoing description in connection with the accompanying drawings, it is manifest that when the cross head is drawn upward from the collar of the shaft, it will move along the inclined rails 7 to one side of the shaft opening, while the bucket itself will be drawn up over the ledges 22 and along the bucket supporting beams 17, the arms 19 of the bucket resting on said beams. The bucket will thus be carried to one side of the shaft and when the arms 19 register with the sockets 23, it is obvious that the hoisting cable may be slightly slackened so as to permit the bucket to automatically discharge its contents. As the arms 19 lodge in the sockets 23, the bucket will be held in the elevated position at one side of the shaft without any danger of its sliding back into the shaft until it is desired that it shall be lowered. For the lowering operation, it is only necessary to ull the bucket upwardly beyond the soc iets 23 which will cause the arms 19 to pass upwardly over the upper ends of the trips 25. As soon as this has been accomplished, the bucket may be lowered, and in passing backwardly over the upper ends of the trips, it will b e deflected from the sockets and permitted to slide downwardly along the beams and into the shaft.

It will thus be seen that I have provided a very simple, durable and efficient construction of gallows frame for mining and eXcavating work generally in which the bucket, as it is hoisted, will be automatically carried to one side of the mouth of the shaft where it may be permitted to discharge its contents without the necessity of employing a laborer to tip it where the contents will be dumped where there will be no liability of their dropping or falling back into the shaft, and without the necessity of employing a man or men at the collar of the shaft to carry the bucket to one side and also without the necessity of employing the doors at the collar of the shaft to close the same, thereby effecting a saving in the maintenance and operation of thea paratus as well as enabling the work to be done more quickly and with more precision than would otherwise be the case.
